Viewsonic VP930b
1. Introduction
Viewsonic is one of the largest and best known manufacturers of CRT and TFT monitors. Viewsonic has a complete product line of TFT monitors, which includes a 19" monitor, the VP930b. We had the opportunity to test this monitor and present our thoughts about it, compared with much lower priced TFT displays from other manufacturers. The main reason we wanted to test the VP930b is that it had some unique features (2xDSUB15 + 1x DVI) as well as pivot, swivel and height adjustment.
- Viewsonic VP930b
Viewsonic has many product lines. The VP930b is characterized as "Pro Series", indicating it is aimed more for professional use.
The main features of the VP930b are:
- ClearMotiv technology: Ultra-fast 8ms (gray-to-gray) video response enables digital HD quality full motion video. Intermediate gray-to-gray, brightness and color changes comprise the vast majority of video transitions.
- Amplified Impulse technology: Advanced amplified impulse technology accelerates grayscale transitions for superior motion video and gaming.
- ThinEdge maximizes your productivity: The ultra-slim 0.67" bezel design enhances your visual experience with clean, minimalist borders around the active image area. Suitable for tiling and stacking. Ideal for multiple-monitor setups.
- PerfectSuite: Professional-grade LCD control software featuring color calibration, asset management, theft deterrence, and auto screen rotation.
- Full 19" viewable screen: 1280x1024 optimum resolution and HD-720p compatible.
- Pivot, swivel, height and wall-mount versatility: VESA wall-mount interface and detachable base for ergonomic flexibility with pivot, tilt, 270 swivel and 5.3"of height adjustment.
- High brightness and contrast: 250-nit brightness (typ) and 1000:1 contrast ratio (typ).
- A safe investment - "Zero Bright Dot":Improved regulation for dealing with pixel errors. VP930 customers can return their product within the DOA period - even if only a single sub-pixel is constantly bright on a dark background.
- XtremeView 170 viewing angles
- Integrated power supply with hard power switch
- Multiple analog/digital inputs expand your connectivity

According to Viewsonic, DOA ( Dead on Arrival) timeframe for return is based on the fact that 99% of such types of sub-pixel errors result within a single normal thermo cycle (i.e. after the display has been on for a period, then off for a period and then on again: hot, cold, hot).
Pixel Defect Policy
From Viewsonic: "...For any sub pixel defect (red or green or blue) ViewSonic LCD display products are warranted in accordance with the ISO standard 13406-2 class II. On pixels ViewSonic exceeds ISO 13406-2 class II requirements not allowing for any defective (permanently dark or bright) complete pixel consisting of red, green, and blue sub pixels (“Zero Pixel Defect Policy”)..." This means you must have at least 2 dead pixels, in order to have a monitor replaced. Below you can see what the ISO standard 13406-2 characterises as class II:
